CO

2

 tests of controlled atmospheres in fruit, 

vegetable, and meat storage rooms. Oxygen 

determination in fl ammable gases. Oxygen tests 

to check atmospheres made inert with nitrogen 

(silos, fuel tanks, etc.)

Flue gas combustion tests, oxygen defi ciency tests, 

and CO

2

 tests of heat treating atmospheres. 

Checking oxygen concentrations in hydrogen-cooled 

generators and oil-sealed inert-gas transformers.

Checking CO

2

 in inert gas blankets in tankers and 

barges carrying gasoline and other com bustibles. 

CO

2

 tests on lime kilns. Checking CO

2

 in sewage 

plant digesters. Oxygen tests in connection with 

oxygen and gas anesthesiology.

For any given fuel, theoretical maximum percent CO

2

 (Ultimate CO

2

 ) would be pro-

duced when exactly enough air (but no excess air whatsoever) is supplied to burn all 

of the fuel. As increasing amounts of excess air are supplied, percentage CO

2

 naturally 

decreases from theoretical Ultimate CO

2

 due to the diluting effect of excess air.

Thus, measuring percent CO

2

 is also a method of indicating excess air to ensure that 

enough is supplied to permit clean combustion without adding so much that combus-

tion effi ciency is unnecessarily decreased.
